BOTTOM-DUMP BUCKET.

Application filed November 21, 1908.

To all whom it may concern: Be it known that I, GEORGE FooH'r, a citizenof the United States, residing at Hoboken, in the county of Hudson andState 7 of New Jersey, have invented a new and useful Bottom-DumpBucket, of which the following is a specification.

This invention has relation to bottom dump buckets, and it consists inthe novel construction and arrangement of its parts, as hereinaftershown and described.

The object of the invention is to provide a bucket as indicated whereinthe bottom may move laterally with relation to the body and tilt duringthe act of dumping, and have reverse movement during the act of closing,means being provided for drawing the bottom tightly against the loweredge of the bucket at the final closing movement, whereby a water-tightstructure is effected.

With the above object in view the invention embodies tracks orguide-ways mounted at the sides of the bucket, and along which pins ofpeculiar configuration are adapted to travel. Lever mechanisms aremounted at the sides of the bucket and are operatively connected withthe said pins and are adapted to move the same along the said tracks;the said lever constructions being of such arrangement that theyconstitute looks when in such positions as will hereinafter appear. Thebucket bottom is pivotally connected with said pins, and may describethe movement indicated as said pins pass along the said tracks.

In the accompanying drawings :Figure 1 is a side elevation of thebucket, showing the bottom closed. Fig. 2 is a side elevation of thebucket, showing the bottom open. Fig. 3 is a front elevation of thebucket, with parts shown in section. Fig. 4 is an enlarged detail endview of one of the pins which connects the bucket bottom with the bodythereof. Fig. 5 is a transverse sectional view of adjacent parts, andshowing one of the said pins in side elevation.

The bucket consists of the body 1, to the upper portion of which isattached the pivoted bail 2, the swinging movement of which is adaptedto be limited by means of the stops 3 which are mounted at the upperedge portion of the said body 1. The lower side edges of the said body 1are ogee shaped Specification of Letters Patent.

as at 4, while the lower forward portion 5 of the front side of the saidbody 1 is inclined toward a median line through the said body, whereby aconstricted opening is formed at the lower portion of the body 1.

The tracks or guides 6 are mounted upon the sides of the body 1, and arepreferably inclined downwardly toward the rear side of the body 1, butthe said tracks may be otherwise disposed, if desired.

The treads 7 of the tracks 6 incline downwardly toward the sides of thebody 1 to which the said tracks are attached. Fig. 5 of the drawingsshows the inclination of the treads of the said tracks, as at 7. Theforward ends of the tracks 6 merge into the upwardly curved extremities8, while the rear ends of the tracks merge into the upwardly curvedextremities 9. The said tracks 6 are preferably mounted upon the plates10, which, in turn, are riveted or otherwise secured to the sides of thebody 1.

The pins 11 are of peculiar configuration, and are provided, at theirinner ends, with laterally disposed flanges 12, which are concentricallyarranged with relation to the eccentric portions 13. The portions 13merge into the concentric portions 14, which, in turn, merge into thereduced, externally screw-threaded portion 15. The square nuts 16 aremounted upon the portions 15 and are held against rotation with relationthereto by means of the locking pins 17, which are transversely disposedwith relation to the said nuts, and occupy registering grooves providedin the said nuts and the portions 15 of the said pins 11. Thefrusto-conical rollers 18 are journaled for rotation upon the eccentricportions 13 0f the said pins 11, and are adapted to travel upon theinclined treads 7 of the tracks 6. The flanges 12 are countersunk in theinner faces of the rollers 18. The concentric portions 14 of the pins 11are journaled for rotation in the end portions of the stirrup 19. Thesaid stirrup 19 passes under the bottom 20 of the bucket, and its endportions lie against the side of the said bottom 20. The floor 21 of thebottom 20 is of ogee configuration, to conform with that configurationat 4 at the lower edges of the sides of the body 1. The angleirons 22are attached at their ends to the front and rear portions of the bottom20, and are adapted to serve as supports for the bucket as an entiretywhen the said bottom is closed against the lower edges of the body 1.

The levers 23 are fulcrumed upon the pins 24, which, in turn, areattached to the sides of the body 1, and the lower ends of the saidlevers 23 are provided with elongated slots 25, which snugly receive thenuts 16, carried by the threaded ends of the pins 11. The links 26 arepivotally connected with the upper ends of the levers 23, and, at theiropposite ends, are provided with shoulders 27. The levers 28 arefulcrumed upon the pins 29, which, in turn, are mounted upon the sidesof the body 1, and the working ends of the levers 28 are pivotallyconnected with the links 26 and are provided with the shoulders 29,which, at times, are adapted to abut against the shoulders 27 of thesaid links 26. The power ends of the levers 28 project in front of theforward side of the body 1, and are connected together by a cross-rod30. Said rod, at an intermediate point, is provided with a laterallydisposed portion 31, which may serve as a handle-grip, and the U-shapedrod 32 is connected at its ends to the ends of the said rod 30.

The brace rod 33 is connected at its upper end with the laterallydisposed portion 31 of the rod 30, and at its lower end to theintermediate portion of the rod 32.

The operation of the bucket is as follows :.WVhen the bottom 20 isclosed against the body 1, the parts are in the positions as indicatedin Fig. 1 of the drawings, in which it will be seen that the power endsof the levers 28 are swung down, and that the working ends thereof areelevated, and that the shoulders 29 and 27 of the levers 28 and links 26abut against each other, and that the pivotal connection between thelevers 28 and links 26 is located above a line connecting the centers ofthe pins 29 and the points of pivotal connection between the links 26and the levers 23. Thus the said links and levers are held in lockedposition. It will also be seen that the power ends of the levers 23 areswung rearwardly with relation to the body 1, and that the working endsthereof are disposed toward the middle of the body 1. Thus the pins 11are held toward the upwardly curved portions 8 of the tracks 6, and thebottom 20 is held firmly against the lower edges of the body 1. When itis desired to swing the bottom 20 with relation to the body 1, the powerends of the levers 28 are elevated, as indicated in Fig. 2, whereby theworking ends of the said levers are swung down, carrying with them theattached ends of the links 26. Thus, the power ends of the levers 23 areswung toward the middle of the body 1, and the working ends of the lastsaid levers are swung away from the middle of the said body. As theworking ends of the levers 23 pass along the tracks 6, the stirrup 19 iscarried toward the ends of the said tracks upon which are mounted theextremities 9, and, by reason of the fact that the for ward portion ofthe bottom 10 is of greater weight than the rear portion thereof, thesaid bottom will tilt into the approximately vertical position, asindicated in Fig. 2. At the same time, the rear portion of the bottom orfloor 21, of the bottom 20 will scrape against the rear edge of the body1, and thus the said rear portion of the floor 20 is relieved ofmaterial. When the bottom 20 is to be closed against the lower edges ofthe body 1, the operation above described is reversed; and, it will beseen that, as the pins 11 move toward the extremities 8 of the tracks 6,the said pins will turn axially with relation to the said tracks, butare held again rotation or turning movement with relation to the levers23; thus, as the bottom 20 arrives at the final stage of its closingmovement, the pins 12 are turned with relation to the tracks 6, wherebythe eccentric portions 13 of the said pins are swung below the axes ofthe pins (as indicated in Fig. 4 of the drawings), and the bottom 20 isdrawn up and held tightly against the lower edges of the body 1. By thisarrangement, it will be seen that a bottom dump bucket is provided whicheffects a Watertight structure when the bottom is closed against thebody.
